"bring to top" worms names

Sometimes the alt+supr option (names transparency) is just useless when you want to see the energy or name of worms that are piled together. You know that when a worm performs an action (like moving under the control of a player, or a passive animation like eating a bit of soil) that worm sprite (including the name) will be brought to the top, in front of the sprites of the other worms of the pile.
If there was a hotkey that could "bring to top" the sprite of one worm (even if it is randomly selected) you could check the names and energy of all the worms of a pile simply by hitting the hotkey enough times. It could be like the "t" key, but instead of affecting the active worm it would force another worm to perform a passive action. Of course, this should be able to affect any worm of any team, and not only your team.
